Metallics JNYN160SS – Frequently Asked Questions
1) What thread size does the Metallics JNYN160SS nylon insert lock nut take?
It's an 8-32 nut, so 32 threads per inch on a #8 machine screw, cut to the ANSI/ASME B1.1 unified thread standard. That means it runs onto any standard #8-32 machine screw, bolt or threaded rod, including the 8-32 screws used on device boxes and cover plates.
2) Will these 8-32 stainless locknuts satisfy a Buy American or ARRA requirement on a public job?
No. The JNYN160SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If the project carries a domestic sourcing clause, this is the wrong line item and you need a domestically produced 8-32 nylon insert nut instead.
3) Is the JNYN160SS locknut actually stainless, and will it corrode outdoors?
The nut body is 18-8 stainless steel, the austenitic grade used for general corrosion resistance in wet and exterior work. If you are in a chloride environment such as coastal or pool chemical exposure, 316 stainless is the grade to ask for instead. Keep in mind the insert is nylon, so the temperature ceiling of the assembly is set by the plastic, not the steel.
4) Can I mix these stainless locknuts with galvanized or plated hardware?
Mechanically yes, any 8-32 male thread will take it. Electrically, pairing 18-8 stainless against zinc plated or galvanized steel in a wet location sets up a galvanic couple and the plating is what gives up first. For exterior or damp installs, keep the screw, nut and strut hardware all stainless.
5) Does this nut meet a published dimensional spec for submittals?
Yes. Dimensions follow ASME B18.16.6 for prevailing torque hex lock nuts, and the threads follow ANSI/ASME B1.1. Hardness is Rockwell B95 to C35. Those three values are usually what a spec reviewer or institutional purchasing group wants on the submittal line.
6) Is a nylon insert locknut the right choice, or should I use a serrated flange nut or thread locker?
For vibrating equipment where you may need to take the joint apart again, the nylon insert is the straightforward pick: no washer to lose, no cure time, and it comes off with a nut driver. A serrated flange nut bites into the mating surface and is better where you want permanent grip and do not care about marring. Chemical thread locker is for cases where heat would soften nylon. This 18-8 stainless 8-32 nut is aimed at electrical, plumbing and HVAC work in high vibration areas.
7) Can these be reused after taking an assembly apart?
Treat them as limited reuse. Prevailing torque comes from the nylon ring being cut and compressed by the male thread the first time it is run on, and the grip drops each time. For anything in a high vibration location, which is what this nut is intended for, fit a fresh one. At 100 to a jar that is not a cost problem.
8) Can I get this nylon insert locknut in other sizes or pack quantities?
Yes. The JNYN series runs beyond the 8-32 size, and other sizes and quantities are available by request. Tell us the thread size and the count you need and we'll quote the matching JNYN part.
